What do you guys think now that the RS 7 is unveiled? Rated at about 560hp, 553tq and 0-60 in 3.9 and 11.8 quarter. Keeping in mind the S8 utilized the same motor with 520hp and 479 tq and weighted roughly 150lb more while achieving a modest 3.5 0-60... I'd expect to see this RS 7 closer to 3.3, maybe even 3.2 in ideal conditions..

I kinda like the new RS7 with the exception of that enormous front grill. The rest of the lines are beautiful though!
As for performance, I'm sure we will see an M6 GC vs RS7 in due time but I would favor the RS7 in the 0-60 department and maybe even the 1/4 mile. I do think the edge may go to the M6 GC on the track though. If I had to pick one, it would be a tough call until I test drove them but going just off of looks, I like the M6 just a bit better..
I can't wait to see these two battle it out

Does anyone know what chasis the M6 GC was built off? Looks so long that they might've used the 7 series? Unless BMW has LWB 6 series they offered in China and used that?

Dimensions wise and weight wise I feel the m6 GC is going to be bigger than heavier. I can't see the RS7 weighing more than 4400lbs which is roughly where the S7 is however I'd be astonished if BMW can keep the M6 GC close to 4,000lbs if earlier posts are accurate.

I agree.
The RS7 look so plain.
Can't tell the difference between this and regular A7 at all.
While the M6 GC is much more aggressive.

You really can't tell the difference from an A7...?!

I've personally found it harder to notice the differences from the M6 to M6 GC aside from the obvious it is longer and has 4 doors. Gorgeous car don't get me wrong but it just seems like a longer M6 Coupe?

Well, the answer is yes. all 5 and 6 series shares the 7 series platform. That is why the 5 and 6 series is so damn heavy. The M6 is heavier than 4000lb and the 6GC will be heavier. BMW shot themselves on the foot on sharing the current platform. There is no excuse for a RWD BMW to be heavier than a similar AWD Audi. But they are!

As for pricing, BMW is got too greedy pricing the 6GC. The 650i GC will be price around the same as the RS7. The M6 GC will be close to $20k more.

One thing everyone seems to forget, once traction is is out of the way, real wheel drive cars have the advantage of not having to share the power to 4 wheels making acceleration better in RWD. You can see in my video where i raced the GTR I totally out accelerated it, actually KILLED it!

Interesting. It'll be awesome to see the 0-100 and 0-120 when finally reviewed. I'd love to see if there was any Porsche influence in the top end.

The one thing I love about the RS 7 though, the retractable spoiler...

Your point is valid, however, at these levels of power/torque, traction remains a factor up to significantly high speeds. Let me start by saying that I absolutely LOVE the M6. It is at the top of my list for my next car, but there are issues that concern me.

With the DSC fully off, you can break traction going into third gear at nearly 100mph (mind you, this is what I have read, it is not from personal experience).

Also, try hammering the throttle in a turn. One of two things will happen. With DSC on, the car will bog. With DSC off, the car will break. Fine on a track in the hands of an experienced driver, but not so fine on the street in the hands of most who will actually be driving this car.

With even the slightest bit of dampness on the pavement, the RS7 and/or GTR will destroy the M6.

So, even if you want to preserve the steering and dynamic advantages of RWD, the M5/M6 are significantly under-tired. These cars should have 275/325 rubber from the factory. A 3200lb Porsche Carrera S, with less than 400lb-ft torque, and the weight of the engine over the drive wheels comes with 295's. This is way too narrow a tire for the 4200lb, front-engine M6.

Bottom line is that at this power level, you need seriously wide rubber, or AWD. Not sure what BMW was thinking here.

As the aftermarket develops for the M6, I am wondering what kind of rubber one will actually be able to fit on the car. This may be a determining factor for me. The stock 265/295 is clearly inadequate IMO.

I came from an A7, which was a great car. Audi did an awesome job with the RS7 design. I like the fact that you can tell it's an RS, unlike the S7. You can definitely notice the difference in traction with the Quattro.

The exterior cues of the S7 are very subtle on the exterior there's no doubt about that, but behind the wheel, that's a whole different story...

The V8 twin turbo vs the V6 superchargerd... Same V8 motor that was in the S6 and beat the M5 in Car and Driver with a 0-60 in 3.7. That's why I can't wait to see the RS 7. Same motor as S8 which Motortrend got a 3.5 0-60.. And with less power, torque and more weight than the RS 7.

I honestly think BMW had a beautiful opportunity here but from solely a performance aspect, I think they missed the bullseye. Just my opinion, I know some of you will disagree.
